The controls took some getting used to and I encountered a couple minor graphical gllitches (Cars parked on a slope stay horizontal so either one end hangs in the air or sinks in the ground stuff like that). It's running surprisingly good on my 4 to 5 year old hardware and looks pretty good at that. So far I played over 12 hours and only barely started the main story because there is just too much to do even in the intro area. A game I'm probably gonna sink hundreds of hours into.
